The system described herein may utilize a data stream connection to detect that a new message is transmitted between users. The system may perform various pre-processing techniques on the new message to identify that the new message is an objection message candidate. The system may retrieve one or parent messages of the new message. The new message and the parent messages may be input into a model trained to classify objection messages. The model may identify that the new message is classified as an objection message based at least in part on processing the new message and the parent messages. An objection classification identifier may be stored in association with the new message based at least in part on the result of the processing by the model.
